DuetWifi Hardware Source Files on Github

  • administrators

    For those of you who want to explore or modify the Duet Wifi hardware the full KiCAD source is now available on Github:

    I will also be updating the documentation to reflect the hardware changes for the production boards

    The source is released under the terms of the License agreement:

    Effectively this is the CERN Open Hardware License version 1.2 with a couple of additional terms to protect our Company Logos and the Duet3d logo.

    Adrian Bowyer and I chose the CERN OHL when developing the Duet 0.6. As a derivative work, the DuetWifi is also distributed under this license. At the time we believed it was the best open hardware license available and I still believe this is true today.

  • Thanks for posting this. It might come in handy down the road.
    I had a look through the schematics and noticed that Fan1 doesn't have the 10k pull-down between the gate and ground like the others have. It probably doesn't matter if the processor has internal pull downs.

    The processor has an internal pull up enabled by default. Fan1 is typically used as a thermostatic hot end fan, so we wanted it to be on by default, in case a user resets the board while the hot end is still hot.

  • Makes perfect sense. I just noticed that "one of these things is not like the other".
